To all whom t may concern.'

Be it known that I, HENRY PIERRE,

a" citizen vof the United States, residing at' vthe ground, created upon the tendency of the An. object of the invention is` to provide means for quickly clamping thedevicfe' in place upon the tires, and capable of taking up all` slack. in the device ywhenin an ap'- plied position; p

vVith these and other objects in view the invention will be better understood from the following detailed description taken inA connection with the accompanying drawings, wherein:

Fig. 1 is a side `elevation of an automobile Wheel withy my .invention applied thereto; i Y i Fig. `2 is a similar view with two of the tread members in the position they assumo when the tire tends to skid; ,y v 'y Fig. 3 is a cross section view through the tire; y

Fig. 4 i device; 3

Fig. 5 is a cross section view ofoneof s an edge view of a portion of the i the members;

the tread of the tire.y The intermediate por- Fig. 6 is an enlarged side elevation of the clamp; i f y Fig.`7 is a cross section view thereof and.

` Fig. 8'is a perspective View ofthe clip.

` Again referring to the drawings illustraty ing the preferred one of the many forms in which the'invention may be constructed a numeral` l designates a plurality of tread members arcuate shape so as to conform to tion of each member isprovided` with vradially extendingjflanges 2 for` engagement with the ground. Links 3 flexibly connect openings el: in the members with chains 5.

engagement of the flanges with the ground will force jthemembers in" a*` direction to bring a gi'eateipoition of eachmember. into engagement,.withrlthe groundl, ,"Itwill yalso be,` notedthata'portion of each vchainl forcedv out of r,its normal position which5.ma,

terially; increases the.v pressure between the upper 'members'and the` tirewthereby absolnt'elypifeventing slipping of the device on thetire.

s A `feature `of `my invention is the clamp 6 which enables me to quickly arrange the device in place and Vtake up any slackness in the chain. yThis clamp consistsA of Aa ratchet element 7 pivotally connected to one end of the chain and the'clip 8 pivotally connected to the other end of the chain. The clip 8 is provided with va guide way 9 r'for the reception of the element 7 and al vslot 10 arranged so as to allow the free end il of the spring 12 to enter the 'slot l() and engage,` anyone of the teeth of the ratchetV element. The spring has an intermediate portion 13 pivoted to a rivet 14 in the clip while itsjremaining end 15 is arranged in recess 16 in the clip, so that theA clip may have'` the proper degree of resiliency in its engagement with the teeth. i

Itis vot coursey to beuunderstood that the invention 'may lbe constructed in various other manners and the parts associated in other relations, and thereforel do not. de-H sire to belimited inany manner except as set forth in the claimshereunto appended.

. What I claimis :1-

PATENT f I be materiallyi'increased whenfithetire .i 4to skid, owingto lthe fact that the frictionalV l. Al chain fastener comprising a looplike guide member carried by one end of a chain, a ratchet membery carried byy the other end of the chain" and sli-dable through said vguide and" formed Witha plurality of notches, a U-shapedA spring secured upon said gulde and having its blght portion en y gageable withln a v selected one of said notchesand seid guide having ai slot for the reception of the bight portion of the spring; 2. ,A chain fastener comprising loop` like guide member carried by one endv of a chain, a ratchet member carried by the other. endl ofthe chainv and slidableuthrough said guide andy formed with .a plurality of i notches, a spring connected with saidvguide, located outside 1t, and having a cross piece engageable within `a selected one' of said vnotches and Said guide having a; slot into which `the bight portion' of the spring e1;-

" tends from the outside.

` 3. A devicev ofjtheclass describedfcomf prising a member having eslottedlhousin at one end thereof, a bar Working insai" slot, a spring for operating said bar placed. futeideof the housingl for holding-'the lbarin the inner part ofthe s1 ot,ftbe .external sides of ythe ,housing acting as guides for jspring, andaV rack bar adapted to be passed throughsaid housing and Yto receive g the cross Vbar between its teeth'.

` '5. A tirechan' lfastener comprising a" t'oothedKrack pvotally attached to one endL of a'chaim ecasing'pvotally attached at 'one' Sidev to thefother` end ofthe chain,"sid

ing and' engaging the` teeth" of v*the rack member, and a sprngpressed member casing ha'virig'fitsends open, whereby the rack can be adjusteoluto a 4positionvin which its end projects beyond. the casing, a. pawlV mo'vable Within said casing, andmeans nfor yieldinglyforcing the pawl yinto eng'agement` kwith thejtoothed rackl upon'finsertion ofthe said racklinto the casing, [for permittin *the* adjustment of the -chain upon the' ve ic1e`` Wheel. r
